Step 1
CO2 +H2 <=> H2CO3 <=> H+ + HCO3-<=> 2H++CO32-
In this equilibrium condition, HCl is added them initially Hydrogen ions concentration increases, which neutralised by carbonate ions present in it to form again bicarbonate and carbonic acid and Equilibrium shifts towards Reactants side, or left side.
Here Le Chatelier's principle is applicable, according to that any change in Equilibrium condition can neutralised by system automatically after some time to minimize the change.
